In order to cut fuel consumption in new diesel engines,Volvo launched VEA,a world-first i-ART technology in new engine family,in 2013 autumn.For i-ART,it doesn't use a traditional single pressure sensor in the common rail and use pressure feedback from each fuel injector to assure continuously monitor and adapt fuel injection per combustion in each of the four cylinders.

"When we add the i-ART technology,it will increase the rail pressure to 2,500 Bar which is recognized to be the the second step in the diesel revolution,"said Derek Crabb, vice president of powertrain engineering at Volvo. “It is a breakthrough comparable to when we invented the Lambda sensor for the catalytic converter in 1976. It's another world-first for Volvo."Crabb also added that each injector has a small computer on top, which monitors injection pressure.The self-adapting i-ART system using this information to assure the ideal amount of fuel is injected during each combustion cycle.

By combining higher injection pressure and i-ART technology,it will bring customers with an engine with improved fuel economy, lower emissions and high performance output as well as a powerful sound character.Volvo will also introduce a new eight-speed automatic gearbox that contributes to a refined drive and better fuel economy.Prediction by reputable common rail parts manufacturers - CHINA -b alin,modular range of diesel and petrol engines would be standard equipped with diesel common rail and petrol direct injection.Several levels of turbo charging open up for the flexibility to cover the whole range from fuel-efficient derivatives through to high power and torque variants. In order to cover all customer requirements, certain engines will also gain added performance via electrification or other spearhead technology.The engines will be built at Volvo's engine plant in Skövde, Sweden.
